A shared socio-economic pathway based framework for characterising future emissions of chemicals to the natural environment

Chemicals are used in all aspects of our lives and either intentionally or unintentionally released into the natural environment, leading to chemical pollution which negatively effects biodiversity ecosystem human health. The world is going through socio-economic, climate technological changes that will affect emissions environment but extent these affects unknown. Scenarios future therefore needed inform research policy decisions protect health humans ecosystems future. In this article, we present a framework, based on Shared Socio-economics Pathways (SSPs) combination with Representative concentration pathways (RCPs), develop environmental scenarios for single molecules groups chemicals sharing similar features. framework has 4 steps: 1) determination characteristics scenario; 2) review prioritisation socio-economics drivers; 3) development scenarios; 4) consistency checks. demonstrated antidepressant insecticide European freshwater-systems 2050.
